Crosswell Seismic ImagingJerry M. Harris, Geophysics Department, Stanford UniversityCrosswell seismic imaging typically operates in a frequency band between200 and 2000 Hz. The images produced from the crosswell geometry providecomplementary coverage and resolution to surface seismic (50 Hz) and borehole logging(10,000 Hz) methods. The broadband signals used in crosswell imaging experiencesignificant dispersion as well time delay during propagation; therefore, the attenuation andthe velocity properties of rocks and fluids may be estimated from the data. In this talk, willreview acquisition procedures and summarize tomographic and reflection processingImethodologiesillustrating(1)for crosswell surveys. In addition, will describe three applicationsthe need for high resolution imaging for aquifers and petroleum reservoirs:Idetermining the geometry;(2) characterization of flow properties, e.g., porosity(3) monitoringfluidmovement andsmall changesinand permeability;saturation.

Feasibility of Reservoir Monitoringby 3-D Surface SeismicBiondo Biondi, Geophysics Department, Stanford UniversityOiland gas production causes changesinthe physical properties of hydrocarbonand temperature, that are, at least inseismic surveys. The knowledge of the evolution of thereservoirs such as: fluid saturation, pore pressure,from reflectionto greatly improve the efficiency of the recovery process.Therefore, monitoring reservoir changes with time-lapse seismic holds the promise tosignificantly improve reservoir characterization and reservoir management. Relating timedependent changes in seismic to the underlying flow processes requires inputs from: (1)principle, "visible"reservoir can beusedgeological modeling/geostatistics; (2) flow simulation; (3) rock physics;imaging. This paperdocuments theand(4)seismicresults from a project that brings these disciplines together. In this studyconsidered the forward modeling for a 3-D reservoir monitoring problem:creating a detailed geological model, performing flow simulation, relating the dynamic rockproperties to seismic properties,and, finally, imaging the reservoir at multiple times.we have

Quantifying theAmountJack Dvorkin andofGas HydratesinMarine SedimentsChristine Ecker, Chevron; andNur, Geophysics Department, Stanford UniversityAmosMarine seismic data and well log measurements at the Blake Ridge offshore SouthCarolina show that prominent seismic Bottom Simulating Reflectors (BSRs) are caused bysediment layers with gas hydrate overlying sediments with free gas. The goal of thisinvestigation is to provide a theoretical tool for quantifying the amount of gas hydrate andgas near a BSR using marine seismic. In order to accomplish this goal, we develop a newtheoretical rock-physics model that links the elastic wave velocities in high-porosity marinesediments to density; porosity; effective pressure; mineralogy; and water, gas, and gashydrate saturation of the pore space. To apply this model to the data, we first obtaininterval velocity using stacking velocity analysis. Then, we use the interval velocitytogether with the rock-physics model to calculate a porosity section under the assumptionthat the entire sediment is water-saturated. Such an inversion gives porosity anomalieswhere gas hydrate and free gas are present (as compared to typical profiles expected andobtained in sediment without gas hydrate or gas). Porosity is underestimated in thehydrate region and is overestimated in the free-gas region. We calculate the porosityresiduals by subtracting a typical (without gas hydrate and gas) porosity profile from thatwith anomalies. Next we use the rock-physics model to eliminate these anomalies byintroducing hydrate or gas saturation. As a result, we obtain a 2D saturation map. Themaximum gas hydrate saturation thus obtained is between 15% and 20% of the porespace (depending on the version o the model used). These saturation values areconsistent with those measured in the Blake Ridge wells (away from the seismic line).Free gas saturation varies between 1%-2%. The saturation estimates are extremelysensitive to the input velocity values. Therefore, accurate velocity analysis is crucial forcorrect reservoir characterization.
